ktm 530 exc-r hard to start

Recommended Posts

I know this has been discussed a lot in the past, but what exactly are the fixes for this bike. How should the jetting be set up right now it is 180 main 45 sec not sure on the needle position. I cut the restrictor off in the exhaust. I am ordering the kit to take the emmisions off. Some one told me some of these had bad cams? It has been like this since new. Any help thanks
